By: R. Gerdes; C. Köberle; F. Kauker; M. Karcher; H. Sumata

Description: Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany. Two types of optimization methods were applied to a parameter optimization problem in a coupled ocean–sea ice model of the Arctic, and applicability and efficiency of the respective methods were examined. One optimization utilizes a finite difference (FD) method based on a traditional gradient descent approach, while the other adopts a micro-genetic algorithm (μGA) as an exampl...
